This paper describes the design and implementation of the distributed digital rights management (DDRM) system as undertaken by the eduSource project, a national network of learning object repositories built by a consortium of universities and other agencies in Canada. DDRM is foremost a system of rights expression, with transactions managed by a set of(More)
The aim of this study was to compare the courses in endodontics and to assess the treatment quality in the student clinics in two dental schools, in Malmö, Sweden and Paris, France. A further aim was to improve the curriculum development in Paris 5 and Malmö by testing student exchange programmes. The comparison was based on the guidelines for undergraduate(More)
In 34 cases of skull traumas and in 14 cases of acute cerebral accidents, CK, GOT, GPT, LDH and its isoenzymes were assessed in the patient's serum and CSF. Results show that the increase of the enzymatic level in the CSF seems due to cerebral tissue damage for the main part, when in the serum the increase is influenced by combined traumas. The CSF dosages(More)
OBJECTIVE To identify similarities and differences in oral health attitudes, behaviour and values among freshman dental students. DESIGN Cross-cultural survey of dental students. SETTING 18 cultural areas. PARTICIPANTS AND METHODS 904 first-year dental students completed the Hiroshima University-Dental Behavioural Inventory (HU-DBI) translated into(More)
Standard Galois Lattices are effective tools for data analysis and knowledge discovery. Several algorithms were proposed to generate concepts of lattices, among which the ScalingNextClosure algorithm. In order to share the production workload between several processors when the number of closed itemsets to determine is very large, this algorithm leans on(More)
Proper isolation is an essential prerequisite for successful endodontic treatment. This article aims to provide an update on the prevalence of rubber dam (RD) use, and the role of education along with attitudes of general dental practitioners (GDPs) and patients towards the application of RD in endodontics. Critical ethical issues are also highlighted.(More)
Standard Galois Lattices are effective tools for data analysis and knowledge discovery. Many research works in classification or association rules increase the interest of them for data mining. They allow structuring data sets, by extracting concepts and rules to deduce concepts from other concepts. They concern binary data arrays, called contexts. Several(More)
Standard Galois Lattices are effective tools for data analysis and knowledge discovery. They allow structuring data sets, by extracting concepts and rules to deduce concepts from other concepts. They focus on binary data arrays, called contexts. Several algorithms were proposed to generate concepts or concept lattices on a data context. However, the mining(More)
